This film is very late 50s, early 60s. Black and white, there's an actor talking to an MIT Professor about digital computers about these new "thinking" machines. The words computer and digital were very exotic at that point.
It's from the “Tomorrow” television series produced by CBS for MIT for MIT’s Centennial in 1961.
